Universal Genève Compax from 1941, 46mm -----> rare silver satin big radium dial by Stern

 Dear watch aficionado.

Here a nice and rare example of a Universal Genève Compax from 1941 in a 46mm case and with the rare silver satin big radium dial by Cadran Stern:

The backside of this original, untouched dial bears the punch mark and code of the dial manufacturer Stern Frères, a master dial maker of the period, famous for their quality and magic of their dials due to little, yet important details in manufacturer. The blank plate is silver galvanized with a vertical satin finish. The recessed subdials are decorated with a fine snailing done by hand with a laze. The plate is covered with a mat transparent lacquer called "sapon" (only on the front, not on the back), which protects against oxidation. Finally all inscriptions are applied by pad printing using different clichés. For the application of the luminescent radium, Stern sent the dial to an external supplier. Only 2 companies existed in Switzerland to do this work. The Lanzett blued steel radium hands were most likely made by Fiedler Geneva, the renowned manufacturer of hands and sole supplier of Stern Frères in this period. The minimal oxidation, especially seen on the contact with the bezel and on the back are natural signs of aging that underline the untouched original condition of the object.

I invite you as well to take a look at my site www.watchcollector.lu for the current offer of vintage and independent timepieces.

NEW available at www.watchcollector.lu -----> Urban Jürgensen reference 1

Dear watch aficionado.

 

NEW NEW NEW NEW available at my boutique www.watchcollector.lu this Urban Jürgensen reference 1 yellow gold with box, outer packaging, UJS strap and buckle:

 

The Urban Jürgensen reference 1 was the first timepiece released under Peter Baumberger and Derek Pratt, after Peter Baumberger acquired Urban Jürgensen in 1979. The reference 1 was a limited edition of only 186 pieces, all in yellow gold and white gold with an exception of 15 platinum examples which were produced later in 2001, released in 1982 and produced until 1986. And there was one example that had been modified by George Daniels with his co-axial escapement.

 

The reference 1 is an automatic chronograph with triple date and moonphase and is based on the Zenith El Primero 3019 PHC. The watch embodies a traditional ethos of watchmaking, the hand-engine turned dial by Derek Pratt which is original Breguet frosted. The Breguet minutes, hours and seconds hands are hand-made of gold. The chronograph seconds hand, 30 minutes and 12 hours counter hands are as well hand-made of flame blued steel. It comes in a 40mm yellow gold case with screw caseback, waterproof, and each single teardrop lug is forged and welded to the case. The pusher at 9 o’clock is for the setting of the moonphase and the pusher at 8 o’clock is for the setting of the day. With the crown set on the second position, the date and month can be set.

 

This example shows the silver day and month windows in English. Whereas there are other examples with the day and month in blue color. The more, this timepiece comes in overall great condition and retains its original box, outer packaging, leather strap and buckle.

Patek Philippe 2584 ----> black épargne dial

 Dear watch aficionado.

Here a nice example of a Patek Philippe 2584 with black épargne dial, of which only two examples are known:

The dial is made by Cadran Stern with the complicated "épargne" technique, which means that first the base plate is gilted, then the signature, minuterie and small seconds are protected by a special lacquer, after that the dial is colored in a black galvanique bath. After the black color has dried, the protective lacquer is taken off. Later the hour baton indexes and the 12 o'clock indexes are added. The indexes are fixed by "pickage" and then leveled by "limage" as you can see on the photo of the dial from the back. This method called "pickage & limage" was used back then at that time. These methods, "épargne, pickage, limage" can be seen as well on famous dials as the Bao Dai.

Rolex 6105 pink gold, black épargne dial

Dear watch aficionado.

 

Here a nice example of a Rolex 6105 pink gold with a beautiful black épargne dial:

 

These black dials were highly complicated to produce. They used the famous épargne method for the minuterie and swiss made signature. After that, the dial was treated in a black galvanic bath and then protected by a so called "sapon", which was a translucent lacquer used for protection against oxidation. The signature "Rolex Oyster Perpetual" & "Officially Certified Chronometer" are made with the décalque doré method by using red gold powder onto the sapon. The sapon on the present example has been "eaten" by the radium lume over the last 70 years, which adds tremendous character. By examining the back of the dial, one can see all the correct details to conclude that the dial is all original. The indexes are fixed by "pickage" and then leveled by "limage" as you can see on the photo of the dial from the back. This method called "pickage & limage" was used back then at that time. These methods, "épargne, pickage, limage" can be seen as well on famous dials as the Bao Dai.

NEW available at my boutique www.watchcollector.lu -----> A. Lange & Söhne Karussell

 

Dear watch aficionado.

 

NEW available at my boutique www.watchcollector.lu this Lange & Söhne Karussell in extraordinary condition

 

The present example, sold to Wilhelm Lenger in Hamburg on April 22, 1914 for 804 Mark, is preserved in excellent condition and certainly one of the best-preserved examples. The three-part enamel dial is free of hairlines, chips or other damage. The heavy pink gold hunter “Lucia” case with its beautiful guilloché and engravings has survived the last century in stunning preservation. The movement is untouched and in perfect condition. The watch comes with the box, and extract from archives (which states as well that the watch was checked at the Lange museum).

 

The Carousel was invented in 1892 by the Danish watchmaker Bonniksen (patent N°21421) and later improved by Richard Lange in 1901 and patented under the number D.R.G.M 121267. It was always the goal of A. Lange & Söhne to increase the precision of a watch in its further developments. This goal was achieved with both, the “Tourbillon” and the “Carousel”. Both ran at Lange & Söhne under the generic term “Drehganguhren”. The Carousel was an interesting alternative to the very costly Tourbillon construction and it was not uncommon for the Lange Carousel watches to achieve a better rate result than the Tourbillons.

 

In these Carousel pocket watches, the advantages of the Tourbillon were used, but on the other side, the disadvantages avoided. Due to the complexity of a Tourbillon, the cage and escapement parts had to be built very fine which resulted in a high fragility. With the invention of the Carousel this fragility was eliminated and with the improved Lange Carousel, which turns at a lower rate at 52 1/2 minutes, the cage and escapement parts could be built very solid and durable. Richard Lange used an improved bearing for the cage, a bigger compensation balance wheel with 16 gold screws of which 2 were for regulation and a steel Breguet spiral spring, lateral gold lever and gold escape wheel, a swan neck fine regulation on the hand engraved balance cock. The beveled and polished blued screws are settled in fine polished oil sinks.
